Researchers have found in a new study that even a moderate level of physical activity can reduce the risk of death in women with breast cancer. This study once once more demonstrates the link between exercise and a reduced risk of developing breast cancer.
Highlights
- Researchers in the study published Thursday in JAMA found that of 315 women diagnosed with breast cancer between 1996 and 2012 in California, the less time they spent engaging in physical activity, the higher the death rate.
- Women surveyed who considered themselves ‘active’ had a death rate of 12.9 per 1,000 person-years (the total number of years of life of the participants analyzed in the study), according to the study.
- The mortality rate rises to 13.4 per 1,000 person-years in women who practice “moderate” physical activity, and to 32.9 per 1,000 person-years in women who consider themselves to have “insufficient” physical activity .

60%. It is the percentage reduction in the risk of death among breast cancer survivors who reported having “moderate” physical activity, compared to participants with “insufficient” physical activity. This finding prompted the researchers to suggest that breast cancer care should incorporate physical activity “because even moderate activity can be vital for prolonging longevity as well as health-related quality of life.”
Contra
Although the study results appear to provide compelling evidence of the link between physical activity and higher survival rates in women diagnosed with breast cancer, the researchers admit that the study faced two limitations. majors. The first was the lack of information regarding the participants’ diets. The second is that the researchers had to rely on participants’ responses to questionnaires regarding their level of physical activity, without the aid of technological devices that might provide quantitative data.
Key Context
Previous studies have shown that a certain level of physical activity can not only reduce mortality rates in breast cancer patients, but also reduce the risk of developing breast cancer. A 2013 study by the American Cancer Society found that walking for at least an hour a day may be enough to reduce the risk of developing breast cancer, with women who walked seven hours a week having a 14% reduced risk. In younger women, however, the link might be less obvious. A 1998 study published in the Journal of the National Cancer Institute found that women who engaged in vigorous physical activity at least twice a week in high school and between the ages of 18 and 22 had only a 1.1% reduced risk. to develop cancer.
Tangent
In the United States, regarding 264,000 women and 2,400 men are diagnosed with breast cancer each year, according to data from the Centers for Disease Control and Prevention (CDC). Breast cancer kills approximately 42,000 women and 500 men each year nationwide.
